4H Electric Camp

Three hundred rising seventh and eight graders from across the state of Tennessee are exploring the world of energy, electricity and the basic sciences at the 2015 4-H Electric Camp. While visiting the University of Tennessee, Knoxville campus, 4-H members will discover the world of electricity by participating in various camp learning centers. These learning centers will be taught on Wednesday and Thursday morning, July 8 and 9, from 8:00 a.m. to 11:55 a.m. These learning centers provide “hands-on” activities where 4-H’ers “learn by doing.” This year’s learning centers feature:

Trouble Light – This learning center will teach you some of the basic wiring techniques that are used by electricians every day. You will have the opportunity to demonstrate what you have learned by wiring up a trouble light which you can take with you to use in your home.

Home Energy Conservation – We use electricity to light our home, cook our food, play music, and operate televisions. But as we use more electricity in our homes, our electric bills rise. In this activity, you will learn how conserving electricity in your home not only helps to lower your electric bill, but also helps to conserve our environment.

STEM Learning Center – So what is STEM? This learning center will increase your knowledge of Science, Technology, Engineering and Math (STEM) principles such as electricity, energy conservation, alternative energy sources, electronics, computer applications, robotics, electrical safety, engineering, and other basic sciences through “hands-on” learning activities.

Electric Vehicles – Campers will learn about batteries, DC current, and how DC current is used to propel electric vehicles. You will also demonstrate your driving skills by maneuvering an electric golf cart through an obstacle course.

Solar Energy – Renewable energy resources reduce the use of fossil fuels and negative impacts on our environment. In this activity, you will learn about how you can use the sun to power things that you use every day. Join us as you discover all about solar energy.

Electrical Safety – Electric power does a tremendous amount of work for us; but, because it is such a powerful force, we must be careful around it. This learning center will teach you how to play it safe around high voltage power lines.

The 4-H Electric Camp is a joint venture of The University of Tennessee Extension; Tennessee Electric Cooperative Association and Tennessee’s electric cooperatives; Tennessee Municipal Electric Power Association and its statewide municipal power systems; and TVA.

Help is on the way when you are in the dark

Electric co-ops serve some of the most rugged, remote terrain in the country, covering more than 70 percent of the nation’s landmass, which means we have learned how to restore power in incredibly difficult circumstances. Now, we’re restoring power even faster. Collectively, electric co-ops have reduced the average time without power their consumer-members experience from 142 minutes in 2011 to 105 minutes in 2013 – a 26 percent decline.

Restoring power is a difficult job and must be done safely and strategically. When the lights go out, Tennessee’s electric co-ops must first assess all damage. Power is always safely restored to the greatest number of members in the shortest amount of time possible. Let’s take a look at the power restoration process.

Repair high-voltage transmission lines

Transmission towers and lines deliver high-voltage power from the Tennessee Valley Authority to local substations, which send power to thousands of consumer-members. If these towers or lines are damaged during a powerful storm or natural disaster, they must be repaired before other parts of the system can operate.

Inspect distribution substation

Distribution substations receive high-voltage power from transmission lines then disperse the power at a lower voltage to the co-op’s main distribution lines. Depending on your electric co-op’s service territory, distribution substations can serve either hundreds or thousands of members. When a major power outage occurs, the co-op’s line crews inspect the substation to determine if the problem stemmed from the transmission lines feeding into the substation, the substation itself or if the problem is further down the line.

Check main distribution lines

If the problem cannot be isolated at a distribution substation, the main distribution lines are checked next. These are the lines you’re most likely familiar with. Distribution lines carry power to large groups of members in your electric co-op’s service territory.

Examine supply and service lines

If local outages persist, supply lines, also known as tap lines, are examined next. These lines deliver power to transformers that are either mounted on poles or placed on pads for underground service. Supply lines can be found outside of homes, businesses and schools. Occasionally, damage will occur on the lines between the nearest transformer and your home. Has your neighbor ever had power when you were left in the dark? This means damage occurred on the service line closest to your home. When the problem is on the service line, it may take line crews additional time to restore power. Remember, power is restored to the greatest number of members in the shortest amount of time possible.

As you can see, restoring power after a major outage is a big job and involves much more than simply flipping a switch or removing a tree from a damaged line. In the event of an outage, your local line crews will restore power as quickly and safely as possible.

Stay safe in the great outdoors this summer

Summer is in full swing, and that means it is time for fun in the sun! As you find yourself spending more time outdoors, Tennessee’s electric cooperatives remind you to stay safe.

Planning a home improvement project? When working outdoors, you may be using tools, such as ladders, power tools, shovels – or even paintbrushes with extendable arms. These items help you get the job done but have the potential to be dangerous if used improperly.

Pay attention to where you place metal ladders or dig for fence posts. Before you start any project, always look up and avoid overhead power lines. Keep a minimum of 10 feet between you and overhead lines.

If you are planning a project that requires digging, remember to dial “811” first to find out if the area you will be working in is clear of underground power lines. Power tools should be kept away from wet surfaces, and outlets should not be overloaded.

Exploring the great outdoors is a great way to spend time with the family, but keep these safety tips in mind.

Children should never climb trees near power lines – always assume a wire is live. Fly kites and remote controlled-airplanes in large open areas like a park or a field, safely away from trees and overhead power lines.

Planning to take a dip in the pool? Electrical devices, such as stereos, should be kept at least 10 feet away from water sources, and outdoor electrical outlets should always be covered. If you hear a rumble of thunder, exit the pool right away.

Speaking of thunder, summer storms can be dangerous if you’re caught in the wrong place at the wrong time. If you find yourself outdoors during a storm, move toward suitable shelter with covered sides, and stick to low-lying ground if possible.

These are just a few tips to remember when you are spending time outdoors this summer with your family. Have some fun out there, and always keep safety in mind!

To seal or not to seal

By Bret Curry

To seal or not to seal the crawl space is a recurring dilemma for many homeowners. To begin, why do homes have crawl spaces? Crawl spaces became a byproduct when concrete block foundations were introduced. They cost less than basements to build, and they provide access to plumbing, ductwork and some electrical components. Decades ago, conventional wisdom introduced vents, and it was believed they would keep the crawl space area dry. However, the vents introduced a few laws of unintended consequences.

But years of field practice by industry experts, a better understanding of building science, the introduction of diagnostic equipment, relative humidity and dew point monitors and infrared cameras have unveiled some compelling facts about crawl spaces. In fact, many builders across the country who understand building science are no longer building vented crawl spaces, and some building codes are even changing to accept properly sealed crawl spaces.

Experience has taught us that a properly sealed crawl space with a properly installed moisture barrier will dramatically reduce unwanted moisture and thwart heat gain and loss. Proper air and moisture sealing improves comfort and reduces heating and cooling costs. Additional benefits are the elimination of the earthy smell inside a home caused by a damp crawl space and elimination of the environment that promotes the growth of mold and mildew – even the floors will be warmer during the winter. Also, properly sealed crawl spaces can be used for storage.

Many existing homes with vented crawl spaces can be retrofitted and sealed if they meet some very important criteria. First, let’s address how nature affects the crawl space. Remember, heat moves to cool on our wonderful planet. On a summer day, our nice cool crawl space becomes an attraction for hot and humid air. The hot air moves through the vents to the cooler crawl space causing everything to become warmer — even the ductwork and floors. If the ground is not properly covered with a moisture barrier, water vapor from the ground and air will condense on cooler surfaces. This is why most ductwork located in vented crawl spaces has evidence of condensation with mold and mildew on the outer side of the insulation. Uninsulated ducts may even show signs of rust and corrosion. The opposite happens during the winter. The warmer air under the floor escapes through the foundation vents. This causes the floors to become quite cold, even causing pipes to freeze and break.

If you can answer “yes” to the questions below about your crawl space, you could be a candidate for sealing:

  • Is your crawl space dry year-round without any standing or recurring drainage problems?
  • Is your home free from any plumbing leaks?

If you answered “yes,” you may consider a sealed crawl space.

Sealing a crawl space is not that difficult, but it does take time to properly complete the job. A rigid moisture barrier is paramount. There are companies that sell quality watertight moisture barriers and special mastics and tapes to assure an airtight and waterproof seal. Foam board can be used for sealing the inner side of the vents.

If you live in an area where radon could be an issue, I suggest contracting with an authorized entity to handle your project. Also, if you live in an area where termites exist and insurance is required, I suggest that you contact your policyholder and inquire about their parameters concerning sealed crawl spaces. They may require a gap between the top of the moisture barrier and the band joist for inspection purposes. Many termite companies now offer this service.

Fill 'er up, please

by Mike Knotts
Director of Government Affairs
Tennessee Electric Cooperative Association

A few weeks ago, when I stopped at the gas station on my way to work to fill up, the math was pretty easy. Ten gallons of gas went in the tank, and the price was $2.50 per gallon. After handing the clerk $25, I drove away and didn’t give it another thought. Several days later, I stopped after midnight to get enough fuel to make it home at the end of a long trip. Once again, 10 gallons of regular unleaded went in, and $25 dollars came out of my wallet. Simple.

When you get gas, you are essentially prepaying for energy your car will use at some point in the future. And it’s easy to visualize what you are paying for because you can see, smell and touch it. A gallon is a familiar unit of measurement. How many gallon jugs of milk have you carried into your home over the years?

For most of us, we don’t put much more thought into paying our electric bill than I did filling up the truck. An envelope arrives in the mail, we open it, write a check and send it in. Or it could be even easier because you have agreed to allow a draft directly from your bank account. Some folks may take a quick look at more of the details that are printed on the bill, but how many fully understand what they’re paying for?

For many years, your co-op has worked very hard to make paying your bill as easy and painless as your trip to the pump. This is despite the fact that purchasing electricity is very different than buying gasoline. Here are three reasons why:

First, electricity is a bit of a mystery. We know it is there, despite being unable to touch, smell or even see it, because we can see the result of its existence. But, as the old adage goes, “Out of sight, out of mind.”

Second, do you know how much energy you are consuming at any given time? In your car, there is a gauge that shows how much fuel is in the tank and probably a display showing your current miles per gallon. But where is the same gauge in your house to show you how much electricity you have consumed? Most of us have very little idea of how much energy our refrigerators, air conditioners, water heaters, ovens, heaters and other major appliances use. So how do we know what it costs when we turn them on? When you open the envelope from your co-op and the bill says you used 1,652 kilowatt-hours of electricity last month, how many milk jugs does that even equate to?

Those are hard questions to answer — but not because there is no equipment that will help you monitor your use. Rather, the question is difficult because our society by and large doesn’t want to know the answer. We have become accustomed to having electric energy available on demand, without exception, at low cost. It’s testament to the hard work of tens of thousands of people whose mission never takes a day off. The luxury that universal electrification affords us as Tennesseans and Americans is not to be taken lightly and has changed the world in so many positive ways over the past 100 years. For that, we should be grateful.

Lastly, there is no practical way for you to purchase and store electricity to be used later (although this could change in the future — see the June 2015 column “Is the future here now?” at tnmagazine.org). When you flip the switch, the electricity you consume is being generated and transmitted to you at that exact same instant. Other common energy sources like wood, gasoline, diesel and even natural gas can be stored in large tanks in preparation for future needs. But to run your air conditioner on a hot July afternoon, you are relying on your electric utility to provide a seamless connection across hundreds of miles of wires to deliver that energy to you at the exact moment you need it — since electricity moves at the speed of light, 671 million miles per hour. This means the cost to generate this energy can be different depending upon the hour of the day, the time of year or even the activities of your neighbors or the factory down the street.

However, technology is advancing at such a rapid pace that the complexity of the electric grid is quickly becoming less of an impediment to the average person’s understanding of his or her own energy consumption. And it is also helping your co-op have a better understanding of how and when entire communities will require their energy — even though the members will continue to demand electricity in real time. With this new information will come better and more transparent methods of paying for our consumption, which I look forward to discussing in a future article.

Energy Independence

by David Callis
Executive Vice President and General Manager
Tennessee Electric Cooperative Association

Last month, a three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit rejected an early challenge to the Environmental Protection Agency’s proposal to curb carbon dioxide emissions from existing power plants, saying the legal action was premature. The panel did not rule on the merits of the lawsuit, stating that objections to the plan were filed too soon because the regulation has not yet been finalized. When the rules are finalized later this year, there will be additional challenges.

The decision was just the latest milestone in the long journey to energy independence. Though it remains unclear if the Clean Power Plan will withstand legal challenges, it doesn’t alter the changes the electric utility industry has undertaken over the past few years.

These changes predated EPA’s Clean Power Plan by several years. Case in point, I wrote the following in The Tennessee Magazine’s July 2007 edition:

We are at the beginning of our own revolution — an energy revolution. Last month, we talked about the changing political landscape and the climate change debate. In fact, it seems that every other headline these days is something about climate change, greenhouse gases, carbon emissions and global warming. The climate change issue has brought about political change — change that will affect us, our children and our grandchildren.

The change won’t occur quickly, that’s for certain. There is no “magic bullet” that is going to solve our energy needs and clean up the environment. Steps toward lowering our energy consumption will go a long way toward lessening our carbon emissions. However, as our population grows, conservation and efficiency can’t solve all of our problems. It will take a long, deliberative process that is going to involve individuals and governments. Developing cost-effective energy alternatives will take a massive technological effort and investment.

Hybrid vehicles, once a novelty item, are rapidly gaining an anchor in the marketplace. Compact fluorescent lamps are quickly replacing incandescent lights in our homes and offices.

There is a long list of renewable energy technologies that today are in their commercial infancy: Solar, wind, geothermal and landfill methane are just a few. As we develop and improve the technologies for harnessing these resources, those energy sources may become more commonplace.

Our current reliable low-emission energy sources — hydro and nuclear — will continue to be a part of our achieving our energy-independence goals. Even coal-fired generation, while contributing to carbon emissions, can be improved through technological advancements that greatly reduce the amount of greenhouse gases emitted.

As we begin this revolution, there is hope for the future. EPRI, the Electric Power Research Institute, suggests “it is technically feasible to slow down and stop the increase in U.S. electric sector carbon dioxide emissions and then eventually reduce them over the next 25 years while meeting the increased demand for electricity.” For example, technologies are currently being developed that would capture and store carbon dioxide in underground caverns.

Those trends have continued — and accelerated — during the past eight years. New housing construction and appliances are even more energy-efficient. Renewable energy resources such as solar and wind are implemented more each year.

Just as our electric cooperatives brought another degree of independence to rural America more than 80 years ago, we remain committed to being involved in a sustainable, renewable energy future as we look toward our nation’s energy independence.

Callis presents at DOE

WASHINGTON, D.C. – David Callis, executive vice president and general manager of the Tennessee Electric Cooperative Association, presented today during the Department of Energy’s Clear Path III, a hurricane preparedness and response event and exercise for the energy sector.

Tennessee’s electric cooperatives routinely provide assistance to neighboring co-ops in Tennessee and surrounding states following natural disasters. “Cooperation is one of the founding principles of electric cooperatives. It is what makes us different from other utilities,” says Callis. “In the hours and days following a natural disaster, we have a responsibility to act with purpose to restore service to our member-owners. It only makes sense to coordinate our efforts and resources to speed the process.”

Deputy Secretary of Energy Elizabeth Sherwood-Randall invited Callis to discuss the electric cooperative mutual aid process as part of a series of information briefs during the event. The objective of Clear Path III is to assess government and industry’s plans, policies and procedures at all levels to identify and improve response efforts.

The Tennessee Electric Cooperative Association provides legislative and communication support for Tennessee’s 23 electric cooperatives and publishes The Tennessee Magazine, the state’s most widely circulated periodical. Visit tnelectric.org or tnmagazine.org to learn more.

A sun-safe summer

Skin cancer is the most common form of cancer in America. As many as one in five Americans will be diagnosed with the disease. People who work outdoors in the summer, including many employees of electric cooperatives, are at even higher risk.

The Tennessee Electric Cooperative Association worked with the American Cancer Society to develop resources to remind co-op employees of the dangers and the simple precautions that should be incorporated into their daily routines.

“Millions of Americans are diagnosed with skin cancer each year. Fortunately, there are some simple precautions that you can take to reduce your risk,” says Greg Broy, spokesperson for the American Cancer Society in Tennessee. “We are pleased to work with the Tennessee Electric Cooperative Association to increase awareness of these precautions for the thousands of electric co-op employees across the state.”

TECA has developed a poster and the infographic below to remind co-op employees to have a sun-safe summer. Order posters for your co-op by contacting Trent Scott at tscott@tnelectric.org.
